1 To'al @from it may conce/ra Be it known that JOHN V37. {Sa/irri` a tus which is exceedingly compact and light 1n order that the same may he readily transported from one placeto another.

In a co ending aialication filed by me May Q9, 1908, Serial No. et, ot which this is ar divisiorn have described and broadly claimed a novel construction ot' a vacuum producing apparatus which is especially adapted to he employed in conjunction With Vacuum cleaners.

it further consists oil. a novel construction of a Vacuum cleaning apparatus wherein a dust separator is employed which is adapted ,to he connected with the cleaning devices ,such as the nozzles, said separator communicating with a vacuum pump which is pro ided with connecting rods operatively connected with the follower head` o'ii the pumping apparatus and 'with a plurality ot' cranks on the motor shaft. l

It further consists of 'a novel construction of a cleaning t evice having a vacuum compartment and a pressure compartment. the pressure.compartment having located therein a suitable motor1 for actuating the vacuum producing mechanism. Which latter is lo cated intermediate 'of the vacuum comparty said casing torming therein a pressure coin- ,of a Vacuum cleaner' which may he employed 'toit cleaning purposes Vin cases in which it is desirable to suck in the dirt and dust by connecting thehose to the inlet and which may also he employed for hloiving the dirt and dust from the articles to he cleaned, in which case the Dhose is connected with the exhaust or outlet.

y lt furtl'ie'rconsists of other novel tea tures of construction, all as will he herein- 'after fully set forth. i

For the purpose of illustrating my'invention l have shown in the accompanying drawings those embodiments thereof which are at present preferred loy me, since the same have been found in practice to give eiiicient and reliable results,V although it is to he understood that the yariousinstrumentalities of which my invention consists can he variously arranged and organized and that my invention is not limited to the precise arrangement and organization ot' these instrumentalities'as herein set forth.

Figure l represents a sectional elevation ot a portable pneumatic cleaning apparatus embodying my invention. Fig. 2 represents a sectional elevation of Fig. l. lFig. 3 represents a sectional elevation of' another emlcodimeut of my invention wherein the tolioiver head of the Vacuum producing apparatus is shown as a piston instead of a diaphragm.

Similar numerals ot' reference indicate :orresponding parts in the igures.

Referring to the dran'ingszdesignates aV hase provided with suitahle rollers Q. whereby the same may he rolled along the iloor when desired, although it is to he understood that my present dei'ice is so light that in practice the rollers may preferably le dispensed with and the derice manually transported from place-to place.

ing devices pass. The outer periphery 'of the diaphragm 14 is held between the flange 17 located at the upper-end .of the casing 3 and the flange 18 located at the lower end of the upper casin 19, it being seen that suitable lfastening evices 20 are' employed,

which pass through the outer periphery of the diaphragm 14 and engage with the flanges'lS and 17, as will be readily apparent from the drawings. The follower head 13 is provided with a spider 21 which is connected withthe boss 22, which latter carries a plate 23, betweenl the outer periphery of which and the follwerhead 13 is located an outlet port- 24, which is controlled by a valve 25, the latter being secured in place by means of a washer 26 and a set screw or equivalent fastening device 27, which passes through said washer 26 andhas engagement with the boss 22. 'The yalve 25 is vpreferablydisk shaped and formedof-a thin plate ol' metal, which is centrally supported so that the annular port 24 is suitably controlled at all times. 28 designates a partition member at the lower portion ofthe ycasing 19, whereby a clearance space is formed between said mem.

ber and the flexible diaphragm 14. The member 28 is provided with ports 30 therethrough which are controlled by means of a valve 31, preferably disk shaped and constructed in a similar manner to the valve 25,

I' said valve 3l being'secured in position by means of a disk or washer 32`and a fastening .device 33, which engages one of thelugs 34 carried by the member. 2 8.

, 35 designates a pan which is removably7 secured to the lugs 34 by means of suitable .fastening devices, such as the screws 36 or 'their equivalents, it being noted that the/diameter-of the'pan 35 'is less than Athe diam- -'etei ofthe' 'vacuumcompartment inthe casing 19., The upper end ofthe casing 19 is I `provided with .an inwardly extending {ian-ge A 37,' which'is'l suitably recessed at its upper end lin order to vreceive a suitable gasket 38 of rubber, leatheror other suitable materialil 39Udes'ig'nat`es a 'cellar 'which is provided ."withaf flanges-40 adapted go be seated on the upperendf of. the casing 9 and engage the 1,1n,oao

gasket 38 in order to form an air tight connection between these two members.

41 designates connections secured to the collar 39 and having .their lower ends secured in any suitable mannerto a dust pan 42 in -which the dust, separated from the dust laden air, is vadapted to be received.

43 designates a bag of canvas or other suitable dust separating fabric which is adapted to be drawn over the dust pan 42 and the connections 41 and secured in place by any suitable means.

44 designates a removable covei' adapted to be seated o n the flange 40 of the collar 39, it being noted that the "cover 44 is suitably recessed as indicated at 45, thereby adapting the same to receive the gasket 46 of rubber,

' leather or, other desired 1naterial. The cover 44 has integral therewith in the present in? stance, an observation glass l7 which 1s prot vided with an air inlet 48, to which latter is adapted to be connectedthe hose secured to the cleaning device, it being noted that the observation glass communicates with the chamber within the casing 19.

49 designates a plate to which is secured a suitable handle 50, it being notedthat said plate 49 rests on the top ofthe cover 44and that rods 51 are provided which are pivotally supported at 52 to the casing 19, said rods 51 being adapted 'to pass through the plate Li9 and be securedin place by means of -the nuts 53. In the embodiment seen in Fig. 3 I have shown a construction in which the follower head or movable member of the pump is shown as being a piston instead of a diaphragm, the only difference in such con-` struction being that the inner end of' the casing 19 -is extended, as indicated at 54 in order to form a piston chamber 55, in which the piston 56 is mounted, said piston being preferably rigidly connected with the con necting rods 9 by means of 'suitable lfastening devices 57. The followerhead 56 is suitably recessedat its periphery in order to receive the packing .58, which is secu'red thereto by means of the ring .59 and suitable fasten-ingl devices 60. The follower head or piston 56 is 'provided with lports 61 there. throughcontroll'ed by a valve 62 centrally supported by means' of the fastening device 63 and the'plate64, as vwill'be readily 'ap-' parent to those skilled in this art, this valve 62 preferably corresponding to the construction similar to the valves 25 and 31.- Y

Since Athe construction of the other parts seen in Fig 3 is similar tfo that already deiis.v

scribed inconnection with Figs'. l1 and 2, I

have deemed it scribe the same.

lvy novel vacuum producing apparatus is in practice made in two styles, the piston type with an oscillating piston and the diaphragni type with an oscillating follower head.

it will new he apparent that l' have devised a novel and useful construction of a portable pneumatic` cleaner, which embodies the -features of advantage enumerated as desirable in the statement of invention and the foregoing description and While l have in the present instance shown and. described apreierred embodiment thereof which gives in practice satisfactory and reliable results, it isto he understood that the saine is susceptible or modificationA in various particulars '-.fvithout departing from the spirit or scope of the inventionor sacrificing any of its advantages.

Having` thus described my invention, what l claim as new and desire to secure by Letters loatent, is:

l. In a pneumatic cleaner, a casing having a pressure compartment and a vacuum compartment' therein, a partition intermediate said compartments having ports therethrough, avalve for controlling said ports, a valve protector located above said ports, we
